Abstract
The possible involvement of calcium in the regulation of methyl jasmonate-promoted senescence of detached rice (Oryza sativa) leaves was investigated. Calcium effectively reduced methyl jasmonate-promoted senescence of detached rice leaves. The effect of methyl jasmonate on the senescence was also significantly reduced by calcium ionophore A23187. Methyl jasmonate-promoted senescence of detached rice leaves may be mediated through blocking the entrance of calcium ions into the cytosol.Keywords
